<p>In order to measure the stare direction, the eyeball (10) is illuminated by means of a light source (14), and there is obtained the eye image containing the image of the pupilla (26) and that of the reflexion of the source (28) on the corneal dioptre and the image is then analyzed in order to determine the position of the center of the pupilla (26) and that of the center of the reflexion (28) to deduce the stare direction with respect to the measurement system. The pupilla edges and the reflection are detected by comparison of the brilliancy difference between successive pixels of the field with a plurality of predetermined reference intervals. The device comprises means (14) for illuminating the eyeball, a camera (22) and eye examination means (54).</p> |
